VersiDrain® 30

What is VersiDrain® 30

VersiDrain® 30 is an interlocking plastic water retention and drainage tray designed to store and drain water under extensive green roof systems.

VersiDrain® 30 trays are positioned on the waterproofing membrane, covered with geotextile, growth media and plants. Water and soluble nutrients become stored in an array of mini reservoirs or cells and are returned to the soil, via capillary action for plant uptake, when required.

VersiDrain® 30 trays incorporate interconnected channels that allow water to flow between the reservoirs. Perforations in the channels allow excess water to flow to drainage outlets.

VersiDrain® 30 protects waterproofing membranes against damage and the high compressive strength effectively supports the weight of growing media, plant species and other weight bearing loads.

VersiDrain® 30 ideal for use under lightweight extensive greenroofs, the 11.6 litres/m2 of stored water reduces the reliance on irrigation.
